Means for transferring hot glass



M. 1, OWENS. MEANS FOR TRANSFERRING HOT GLASS.

APPLICAUON FILED APR.I5,1918.

PatentetiAug. 24. 1920.

INVENTOR engages a tooth. on the ratchetwheel and -the glass and said. surface.

rotates the latter until the dog slips past.

the tooth. lDuring the return of the bar the .dog: can yield inwardly as it moves down-' ward past the next tooth of the ratchet wheel. A'spring actuated detent 3% seats in recesses 35 in the shaft 17 and yieldingly holds the multiple trough in position, preventing overthrowof the trough and also preventing backward rotation thereof.

' Means are provided for supplying moisture to the conveying surfaces to prevent overheating and to provide a damp surface for the glass to slide along. The hotglass instantly vaporizes any moisture with which it comes in contact on the conveying surface and thus forms a thin gaseous film between The moisture may be supplied in various way. As herein shown, a pipe 36 beneath the transfer device and extending lengthwise thereof is provided with openings through which water 37 is sprayed against the under surface of the transfer device. e

'A suitably shaped funnel orguide 38 is arranged at theJower end of the conveyer for directing the gobs of glass into. the molds 16. Said molds may be carried on a rotary mold frame forming part of the glass forming machine. The driveshaft 1.0 is connected to rotate in synchronism with said machine sothat a gob of glass is discharged into each mold 16. The parts are so timed that the divided cup and cut-off 8 and 9 operate to drop a charge of glass on the trough 21. while the latter is stationary. The glass quickly slides down the trough and into the mold 16. While the next charge is accumulatingin the cup 8, the cam 28 operates the bar 26 to rotate the transfer device through 90 degrees, bringing the next trough up to position. The detent 3% then snaps into position to hold the trough stationary until it is again advanced by the driving cam.

Although the'transfer device is given a step rotation for each gob or charge of glass, it willfbe understood that the intervals between the step rotations may be varied. For example, it might be rotated one step after every second or third gob of glass discharged thereon. v

Modifications may be resorted to without departing from the spirit and scope of my invention.

.What I claim is:

1;.A rotatable transfer device comprising a number of conveying surfaces arran ed about its axis of rotation and extending lengthwise thereof, and means to rotate said device step-by-step and thereby bring said surfaces serially into operative position.

2. Transfer mechanism comprising a number of troughs or chutes, a support onwhich said chutes are mounted, and means to rotate the support step-by-step about an axis and thereby bring the chutes successively to operative position, said chute extending lengthwise of said axis.

Transfer mechanism comprising a number of troughs or chutes, a support for said chutes, means to rotate the support step-bystep about an'axis and thereby bring the chutes successively to operative position, said chutes extending lengthwise of said axis, and means to supply moisture to the surface of the chutes.

4:. Transfer apparatus comprising a plurality of troughs arranged symmetrically about a common axis of rotation, and means to rotate said apparatus about said axis and thereby bring the troughs successively to inclined position, each trough being formed to convey articles in a'direction lying in a plane of said axis.

5. A rotatable transfer device comprising a number of conveying surfaces arranged about its axis of rotation and extending lengthwise thereof, a toothed wheel carried by said device, and a driving dog to actuate said wheel and thereby rotate the transfer device step-by-step.

6. A rotatable transfer device comprising a number of conveying surfaces arranged about its axis of rotation and extending lengthwise thereof, a toothed wheel carried by saiddevice, a driving dog to actuate said wheel and thereby rotate the transfer clevice step-by-step, and a spring detent to hold said device in' a fixed. position after each step rotation.

7. The combination with means for segregating molten glass into individual masses or gobs, of means to receive the gobs, and mechanism to transfer the gobs to said receiving means, said mechanism comprising a plurality of inclined chutes arranged about a common axis of rotation, and means to rotate the chutes step-by-step about said axis and thereby bring them successively to position to receive a gob and direct it to said receiving means. 4

8. The combination with means for segregating molten glass into individual masses or gobs, of means to receive the gobs, and mechanism. to transfer the gobs to said receiving means, said mechanism comprising a plurality of chutes arranged about a common axis of rotation, means to rotate the chutes step-by-step about said axis and thereby bring them. successlvely to operative posiliquid to the trough while out of said receiving position.

10. The combination of a chute or trough, means to deliver hot glass thereto, means to rotate the trough about an axis extending to thereby bring the a glass receiving posiposition, and means to liquid to the trough While trough alternately to tion and an inverted apply a cooling inverted.

11. The combination with means for segregating molten glass into individual masses or gobs, of means to receive the gobs, and mechanism to transfer the gobs to said receiving means, said mechanism comprising an inclined support, a plurality of troughs or chutes carried by the support and extending lengthwise thereof, means to rotate the support step-by-step whereby the troughs are successively brought to operative position, and means to spray the conveying surfaces with a cooling liquid While out of conveying position.

12. The combination of a trough, means to deliver hot glass thereto, and means to revolve the trough about an axis extending lengthwise of the trough.
